High temperature and high pressure forged steel globe valve
High temperature and high pressure stop valve is widely used in various working conditions of steam water medium pipeline and petroleum, chemical, metallurgical and other medium pipeline, used for media closure isolation
Application
High temperature and high pressure stop valve is widely used in various working conditions of steam water medium pipeline and petroleum, chemical, metallurgical and other medium pipeline, used for media closure isolation. This series of valves belong to our company "Nantong type" globe valve classic products.
Characteristic
• Body adopts full forging process, uniform structure, beautiful appearance, no structure defects;
• Compact valve with bonnet less design;
• Cobalt-based hard alloy is surfacing on the sealing surface to ensure high and poor hardness, wear and corrosion resistance, and effectively prolong the service life;
• Disc according to customer requirements can be used as a whole hard alloy ball, scour resistance, free rotation of the ball with self in the function, sealing more reliable;
• The surface of the valve stem is treated with corrosion resistance and abrasion resistance, which can effectively reduce the opening and closing moment and make the operation easier;
• Driving mode: manual, electric, pneumatic and other driving forms.
